Abstract

La présente invention concerne un procédé de mesurage, un dispositif terminal, et un dispositif de réseau. Le procédé est appliqué dans un dispositif terminal comprenant une pluralité de faisceaux de réception, et comprend les étapes consistant à : diviser la pluralité de faisceaux de réception en une pluralité de groupes de faisceaux de réception, la pluralité de groupes de faisceaux de réception utilisant différents paramètres de mesurage, les faisceaux de réception dans chaque groupe de faisceaux de réception utilisant le même paramètre de mesurage, et le dispositif terminal utilisant le paramètre de mesurage pour effectuer un mesurage de gestion de ressources radio (RRM) ; et exécuter un mesurage RRM sur chaque faisceau de réception des groupes respectifs de faisceaux de réception sur la base des paramètres de mesurage des groupes respectifs de faisceaux de réception. Dans le procédé de mesurage décrit dans un mode de réalisation de la présente invention, la division d'une pluralité de faisceaux de réception d'un dispositif terminal en groupes et l'exécution d'un mesurage sur la pluralité de faisceaux de réception sur la base de paramètres de mesurage des groupes respectifs de faisceaux de réception peuvent réduire efficacement le surdébit temporel provoqué lorsque le dispositif terminal exécute un mesurage sur les faisceaux de réception.
